Water flow rate adjustment:
• Connect a hydraulic pressure gauge to the ¼’’ SAE pressure
taps at the inlet and the outlet of the circulating pump in order to
measure the differential pressure.
• Adjust the red knob to the maximum pressure
• Take the differential pressure measurement ∆Pm and record
The corresponding flow rate value Qm on the envelope curve
of the circulating pump
